Abstract :
The magnesium, being one of the most important metabolic elements, has a very major function in the animals growing processes. Also magnesium has a function in structure and operation of many important enzymes which are effective in metabolic reactions of body. Reduction of serum magnesium rate may conduce to weakness of immune system, increase of sensitivity to infectious diseases, growth drop, sexual and breeding disorders, etc. In this study, during four seasons of year, the bleed accomplished by using venoject tubes (obtained from jugular vein) from sample randomly, on 400 pregnant cross breed cow, apparently healthy at Tabriz abattoir. Immediately, all of the blood samples were transferred to laboratory beside the ice packs. The end of each season, after centrifuging, the serum mg levels were measured by Randox biochemical kit, and using the spectrophotometry method and then results analysed. In this study mean serumal rate of magnesium varied in different seasons (there was a correlation between Mg levels and seasonal temperature changes). The lowest level of Mg was measured in winter that according to statistical analysis (ANOVA, P<0.001) these variations statistically was significant. Results of recent study also showed that there is a significant correlation between the age of dairy cattles and their serumal Mg levels (elder cattles had higher serumal levels of Mg, P<0.001). According to results of pierson correlation ratio test there was not significant relation between fetus age of pregnant cows and Mg levels. This clear reduction Mg level of serum in winter may be the result of excessive using hay in diet, on available to green grass and also the excessive cold weather in winter.
